Opis:
The utility of phytocenotic indices in the diagnosis and classification of forest sites might be limited because of vegetation degeneration in managed forests. However, even in secondary communities it may be possible to determine indicator species, although these may differ from typical and well known plant indicators. The aim of this work was to assess the vegetation diversity of Scots pine stands in representative forest site types along a moisture and fertility gradient. In total 120 sample plots from Turawa forests were included in the study. These plots represented young (21–40 years) and old (> 80 years) Scots-pine-dominated stands. The forest sites were categorized according to Polish site classification. Four site categories were studied: Boew (very nutrient-poor and mesic sites), BMoew (nutrient-poor and mesic sites), BMw (nutrient-poor and moist sites), LMw (quite nutrient-rich and moist sites). The species composition of the forest patches studied hardly differed among forest site types. Almost all of the vegetation in site Boew was different from both moist site types (BMw and LMw). Sites Boew andLMwhad the exclusive species determined as site indicators. Moreover, young stands had their own site type indicator species which differed from old stands. Numerical classification showed that only two plant communities were widespread: Leucobryo-Pinetum in Boew and BMoew, and the community of Pinus sylvestris and Molinia caerulea in BMoew, BMw, LMw. In secondary communities typical indicator species may not be useful, but it is possible to determinate species that are locally unique to forest site type. Despite the convergence in the composition of the plant community resulting from tree stand unification, plant communities have the capacity for a more diverse composition. Tree stand conversion can increase phytocenotic diversity.

Opis:
The paper analyses the relationships between the microsite diversity of fresh coniferous forest and the number of Scots pine (Pinus sylvestris L.) seedlings from natural regeneration. The competition of forest floor vegetation (mainly of Vaccinium myrtillus) was found to be the decisive factor of pine regeneration. Lichens, especially Cladonia arbuscula and C. rangiferina, as well as mosses, e. g. broom moss (Dicranum scoparium) and pincushion moss (Leucobryum glaucum), can be regarded as the indicator species for the microsite suitable for pine regeneration.

ecological indicator value
Opis:
The paper discusses the impact of clear−cutting and artificial regeneration on species composition of the fresh coniferous Vaccinio vitis−idaeae – Pinetum association Sokoł. 1981. The studies were conducted in the maturing artificially established stands (of 55−77 years) and 150−180 year−old natural old−growth stands in the Polish and Belarusian part of the Białowieża Primeval Forest. No quantitative and qualitative differences were found in species composition and structure between the two groups of stands. The lack of significant differences between the two development stages was ascertained using ecological indicator values. In the maturing stands the non−forest species were not found, and all species (so−called euphytes??), characteristic of the Vaccinio vitis−idaeae – Pinetum association, were already present there. This means that the use of a clear cutting system emulating the catastrophic natural disturbance pattern of forest dynamics in this association did not entail permanent changes in the ground vegetation.

Opis:
The resilience of forest ecosystems to climate changes such as elevated temperature and frequent drought episodes, strongly depends on how the soil subsystems and its inhabitants responds to these perturbation. The epigeic soil Collembola communities of mature mixed deciduous forest and adjacent young plantation on moderately humid soil were compared in two consecutive years, out of which the second one was marked by significant deficiency of precipitation in growing− −season. The study plots were established on the area of experimental forests of Warsaw University of Life Science−SGGW in Rogów (central Poland). The objectives of the study was to assess the sensitivity of forest Collembola communities to drought stress and to check if the reaction depends on stand age. We also aimed to test if an indicator species of climate changes can be appointed. The results showed that three months drought episode had negative impact on forest Collembola communities of mature stands, while communities of young plantation were not affected. The reduction of total abundance of Collembola and clear changes in communities structure in mature stand was detected in the year of lower precipitation. The Collembola communities of young plantation were also significantly transformed, but in result of clear cutting and soil preparation. Therefore, the successional changes were the most evident process in these communities and there were no signs of drought influence. Among the most numerous species in Collembola communities of mature forest Isotomiella minor was appointed as an indicator of drought, because its abundance was drastically reduced in the year of lower precipitation. The small number of specimen of this species in young plantation may also prove its sensitivity to deficiency of humidity in soil. The significantly negative response to drought episode was documented also for Psuedosinella horaki, Micraphorura absoloni and Megalothorax minimus. Our study provided strong evidence that the drought, which lasted only three months, had a detrimental effect on forest Collembola commu− nities.

Opis:
The paper presents the results of water trophy assessment from various stations of the cooling system of the “Dolna Odra” (Poland) power plant. The assessment was made based on the indicator phytoplankton species collected four times at four sites located in different parts of the hydrological system cooling the technical infrastructure of the power plant. The sites were characterised by water with a natural temperature for individual seasons, as well as by thermals changed as a result of the discharge of cooling waters. For each site, the saprobic index was calculated based on indicator species. The analysis showed that the changes in trophic conditions, both in waters with changed thermals and in waters not subject to the influence of after-cool waters, are not subject to significant changes. The waters of all studied sites in the analysed periods of the year should be classified according to Sladeček and Sládečková (1996) to the waters of the β–mesosaprobic zone, with a saprobic index value ranging from 1.51 to 2.50 (average S = 2.0). This zone is characterised by the course of biochemical processes under aerobic conditions, as a result of which complete oxidation of the intermediate products of decomposition of organic compounds takes place.
W pracy przedstawiono wyniki oceny trofii wód z różnych stanowisk układu chłodniczego elektrowni „Dolna Odra” (Polska). Oceny dokonano w oparciu o wskaźnikowe gatunki fitoplanktonu zebranego w czterech terminach roku na czterech stanowiskach, zlokalizowanych w różnych częściach systemu hydrologicznego, schładzającego infrastrukturę techniczną elektrowni. Stanowiska charakteryzowały się wodami o temperaturze naturalnej dla poszczególnych pór roku, jak i zmienną termiką w wyniku zrzutu wód pochłodniczych. Dla każdego stanowiska obliczono indeks saprobowy na podstawie gatunków wskaźnikowych. Analiza wykazała, że zmiany w zakresie trofii, zarówno w wodach o zmienionej termice, jak i wodach nie podlegających oddziaływaniu wód pochodniczych, nie ulegają istotnym zmianom. Wody wszystkich badanych stanowisk w analizowanych okresach roku należy zaklasyfikować wg Sladeček i Sládečková (1996) do wód strefy β–me- zosaprobowej, mających wartość indeksu saprobowości w granicach od 1,51 do 2,50 (średnio S = 2,0). Strefa ta charakteryzuje się przebiegiem procesów biochemicznych w warunkach aerobowych, w wyniku których zachodzi całkowite utlenienie pośrednich produktów rozkładu związków organicznych.

Opis:
During the survey of the Mały Borek nature reserve (Augustów Forest, NE Poland) 236 species of vascular plants were recorded, including 10 plant species red-listed in Poland and 19 species protected under the Polish law. The most valuable species were sedges typical of the boreal coniferous forests: Carex vaginata, C. globularis and C. loliacea. The presence of neophytes was very limited (1,3% of the flora) in the area studied. The principal aim of the establishment of the reserve was the conservation of old-growth coniferous forests with long ecological continuity. Since the reserve studied consists mainly of old-growth coniferous forests, the number of species regarded as ancient forest indicators is lower (54 species) than in the well-preserved reserves with deciduous stands in north-east Poland, but still rather high. The most valuable, threatened species are bound to wetland forests that are presently disturbed due to drainage. Restoration of the former hydrological conditions is essential for the preservation of the vascular plants in the reserve.

Opis:
Vegetation of deciduous forests in the Štiavnické vrchy Mts (Central Slovakia) was studied using the standard Zürich-Montpellier approach. The numerical classification and ordination technique were applied to determine the main forest vegetation types and to find the responsible environmental drivers related to their distribution patterns, respectively. The data set including 198 relevés collected by authors in 1997-2009 and 185 relevés excerpted from literature was used to analysis. Numerical classification resulted in delimitation of fourteen vegetation types representing eleven associations with two variants and two communities within the Quercetea roboripetraeae and Querco-Fagetea classes. The major environmental gradients in variation of forest species composition were associated with moisture and nutrient content following the average Ellenberg indicator values. Along the moisture gradient, vegetation types were ordered from subxerophilous oak forests turn mesophilous mixed oak-hornbeam, beech and ravine forests to hygrophilous riparian alder forest. The results confirmed important role of soil nutrients and moisture by determination of forest vegetation in subcontinental part of Central Europe. Special attention was given to the discussion of floristical characteristics, site conditions and syntaxonomy.

Opis:
Seslerio uliginosae-Scorzoneretum purpureae is the only xerothermic community of the Festuco-Brometea class, where a rare species known as Sesleria uliginosa occurs in Poland. A couple of sites hosting this association in the Nida Basin were described in the 1920s and 1950s. All these stands are now situated in the areas designated as xerothermic nature reserves. The study aimed at describing the present-day characteristics of this rare association, the most likely being endemic in Poland, as well as the changes that have occurred in it. The species diversity and the contribution of xerothermic plants have decreased significantly in terms of their number and cover coefficient. Some of the diagnostic species of the association have become extremely rare. Sesleria uliginosa is the only one without visible changes in their dominant position in the community. Mosses, that have played a significant role before, were among the vanished species. At the same time, an increase in number and cover of mesophilous meadows species was observed. Mesophilous grasses belong to the group of species growing in significance in the phytocoenoses. The observed changes in species composition were reflected in a statistically significant increase of nitrogen indicator value. The slow process of succession observed in the Seslerio-Scorzoneretum purpureae could be attributed to the lack of appropriate land use, e.g. mowing and grazing that have been ceased in the nature reserves.

Opis:
The intensity of disturbance plays a key role in shaping the biodiversity and hence it is a good tool for assessing community changes occurring in the Western Bieszczady, an area depopulated after World War II. Based on sampling of acidophilous mountain beech forest phytocoenosis repeated after 50 years, an analysis of plant biodiversity changes was conducted. The study focused on changes in the number of species, Shannon’s indicator, spatial distribution and coverage of specific ecological groups of species. The results confirm an undergoing process of regeneration of straitened phytocoenoses from 1958−1961, in which a slow improvement of the trophic conditions can be observed.

Opis:
Gmina Uniejów to obszar rolniczy – ponad 80% jej powierzchni stanowią użytki rolne, a lesistość wynosi obecnie 10,6%. Jest to teren ubogi w lasy, które na obszarze gminy są w znacznym stopniu rozdrobnione, a ich roślinność antropogenicznie zaburzona. Brakuje większych kompleksów leśnych. W latach 2021–2022 przeprowadzono inwentaryzację flory w 33 wybranych losowo wyspach leśnych, których powierzchnia była mniejsza niż 10 ha. Oceniono przyrodniczą wartość badanych obiektów, wykorzystując gatunki wskaźnikowe („rośliny starych lasów”). W badanych wyspach leśnych odnotowano 21 gatunków roślin typowych dla starych lasów. W najbogatszym florystycznie obiekcie stwierdzono 10 gatunków wskaźnikowych dla starych lasów, a w najuboższych tylko po dwa tego typu taksony. Wyspy leśne gminy Uniejów cechują się małą liczbą gatunków typowych dla starych lasów. W większości są to obiekty wtórne na gruntach użytkowanych w przeszłości rolniczo.
Uniejów agricultural landscapes dominate in the Uniejów municipality as farmland takes up more than 80% of the area, while woodland constitutes only 10.6% and is reduced to separate small wooded patches (islands) with anthropogenically impaired flora. No larger forest tracts survived there. In the years 2021–2022, the flora of 33 randomly chosen forest islands (less than 10 ha) was examined and listed, focusing particularly on species belonging to the group of “ancient woodland indicators”. Altogether 21 species of plants typical of old forests were identified in the area, out of which 10 species were found in the “richest” forest patch and only two in the poorest one. Generally, forest islands in the Uniejów municipality contain few species confined to old forests. The islands represent mostly recent secondary woods on the formerly agricultural land.

Opis:
This paper presents an overview of bird research carried out in the Borki Primeval Forest during the last 30 years. The Borki Primeval Forest can be considered as one of the most important forest bird sites in Poland. Its avifauna comprises 139 breeding species, including 11 rare and endangered species listed in the Polish Red Data Book of Animals as well as 30 species listed in Annex I of the EU Birds Directive. Despite its relatively small area, the Borki Primeval Forest holds at least 1% of Polish breeding population of as many as 12 bird species . For seven out of these species it is one of the most important breeding sites in the country. The avifauna of the Borki Primeval Forest consists mostly of typical forest birds including 24 indicator species which are associated with natural forests. The richness of bird species in the Borki Primeval Forest and the abundance of several valuable groups of breeding species are the result of a high landscape and habitat diversity as well as a relatively small anthropopression combined with a high degree of naturalness of forest stands.

Opis:
The species composition and size-structure of the phytoplankton community in the Boka Kotorska Bay (SE Adriatic Sea) were analysed with respect to abundance and carbon biomass, together with the physico-chemical parameters, with the aim of evaluating the predefined oligo-mesotrophic status of this transitional water ecosystem. Three stations located in the inner part of the Bay were sampled with seasonal frequency in 2008/2009. Picophytoplankton cells were counted using flow cytometry; nanophytoplankton and microphytoplankton were identified and counted by light microscopy. The relative importance of the picoplankton in the Bay, in terms of both abundance and biomass, during all the investigated seasons emphasized their significance in the phytoplankton community. Picocyanobacteria (Synechococcus) constituted a significant part of the summer assemblages with regard to both abundance (up to 3.38 × 108 cells L−1) and carbon biomass (up to 73% of total phytoplankton carbon). The contribution of the nanophytoplankton was found to be generally low (<20% of the total phytoplankton carbon) in all seasons, and was dominated by autotrophic/mixotrophic flagellates. Species with a preference towards nutrient-enriched conditions, like the diatom Skeletonema marinoi, dominated the microphytoplankton fraction. S. marinoi was the most abundant in spring/winter (up to 2.86×106 cells L−1) above the halocline (making a 96% contribution to the microphytoplankton). The potentially toxin-producing diatom Pseudo-nitzschia pseudodelicatissima was recorded at abundances greater than 105 cells L−1, together with Thalassionema frauenfeldii, as well as the dinoflagellates Prorocentrum micans and the potentially harmful P. minimum. The higher values of phytoplankton biomass and the dominance of phytoplankton species or groups with preferences for nutrient-enriched conditions appear to be consistent with the oligo-mesotrophic status of this specific ecosystem.
